3 sap(integrate legacy with XI - Inbound and outbound proxy
We are planning to have 3 sap (SRM,BI and CRM) systems to integrate with legacy systems . All the systems have inbound as well as outbound proxy calls. I have few questions:
1.What are the different steps to be configured to make this scenario work with one XI instance .
Does any one have this kind of scenario.
I know we can do it without proxy calls .
Awarded for appropriate solution.
